I installed my flip top case correctly on my PS2. I connect wires and such, put game disc in (from the flip lid) and it says 'disc loading' for a very long time and nothing happens. Then I reset the PS2 and there is a mad noise. I open the lid and I see the disc spinning really fast and its 'jumping'. This happens to all discs. So I try putting back my normal PS2 case, and try a game. It works. What have I done wrong? Help please!
